Answer:
The invention of active drug loading method improves the encapsulation efficiency of some ionizable hydrophilic drugs (weak acid or weak base). The specific method is to construct pH gradient inside and outside the liposome, and then use the solubility difference of ionizable drugs under different pH conditions to realize the drug loading. With this method, the drug encapsulation rate can reach more than 95% and the drug loading can reach about 10%.

What is transported is the water in the currents. Like the water in the currents is moving in a direction, another thing that is transported is trash and other such stuff that gets caught in the current.
An observation may generate a scientific question, which may lead to a hypothesis. The hypothesis can be tested the experimentation. The results of experimentation lead to changes in scientific knowledge.
